Segmental testicular infarction: report of seven new cases and literature review

Segmental testicular infarction is a relatively rare acute or subacute condition which is infrequently thought of in the differential diagnosis for testicular pain. However, missing or misdiagnosing this entity on clinical evaluation and/or imaging has significant implications for patients as they may undergo unnecessary surgery for suspected testicular torsion or tumor. Knowledge and recognition of the features of segmental testicular infarction on ultrasound and MRI will aid in the diagnosis of this disease early in the patient's course. The common imaging features of segmental testicular infarction and the clinical literature are reviewed, with an emphasis on ultrasound, utilizing seven recent cases from three institutions.
